Comment 9 for bug 442157

Seems to me from the debian/control file that this (--with-default-audiosink=autoaudiosink) is already set for gstreamer0.10-plugins-good:

ifeq ($(DEB_HOST_ARCH_OS),linux)
DEFAULT_AUDIOSINK = autoaudiosink
DEFAULT_AUDIOSRC = alsasrc
DEFAULT_VIDEOSINK = autovideosink
DEFAULT_VIDEOSRC = v4l2src
DEFAULT_VISUALIZER = goom
else
DEFAULT_AUDIOSINK = autoaudiosink
DEFAULT_AUDIOSRC = osssrc
DEFAULT_VIDEOSINK = autovideosink
DEFAULT_VIDEOSRC = videotestsrc
DEFAULT_VISUALIZER = goom
endif
